The myometrium is located between the endometrium (the inner layer of the uterine wall) and the serosa or perimetrium (the outer uterine layer).. The inner one-third of the myometrium (termed the junctional or sub-endometrial layer) appears to be derived from the Müllerian duct, while the outer, more predominant layer of the myometrium appears to originate from non-Müllerian tissue and is ...
Translational vascularity - diffuse spread of small vessels within the myometrium; Irregular or interrupted junctional zone - the borderline between the endometrium and myometrium; The power Doppler or Doppler ultrasonography function can be used during transvaginal ultrasonography to help differentiate adenomyomas from uterine fibroids.
A uterine fibroid can cause rectal pressure. The abdomen can grow larger mimicking the appearance of pregnancy. [1] Some large fibroids can extend out through the cervix and vagina. [8] While fibroids are common, they are not a typical cause for infertility, accounting for about 3% of reasons why a woman may not be able to have a child. [11]
A medical condition is termed heterogeneous, or a heterogeneous disease, if it has several etiologies (root causes); as opposed to homogeneous conditions, which have the same root cause for all patients in a given group. Examples of heterogeneous conditions are hepatitis and diabetes. Heterogeneity is not unusual, as medical conditions are ...
From innermost to outermost, these layers are the endometrium, myometrium, and perimetrium. [7] The endometrium is the inner epithelial layer, along with its mucous membrane, of the mammalian uterus. It has a basal layer and a functional layer; the functional layer thickens and then is shed during the menstrual cycle or estrous cycle.
A retroverted uterus (tilted uterus, tipped uterus) is a uterus that is oriented posteriorly, towards the rectum in the back of the body. This is in contrast to the typical uterus, which is oriented forward (slightly "anteverted") toward the bladder, with the anterior part slightly concave.
Adenomyoma is a tumor (-oma) including components derived from glands (adeno-) and muscle (-my-). [1] It is a type of complex and mixed tumor, and several variants have been described in the medical literature.
The decidua is the modified mucosal lining of the uterus (that is, modified endometrium) that forms every month, in preparation for pregnancy.It is shed off each month when there is no fertilized egg to support. [1]
